If you have already registered you should receive instructions via email on how to pay and where to send payment.If you haven't registered you can do so here. Bear in mind that the match is full and you will be out on the wait list.

I did register night of, received email from MatchDirector confirming registration, but did not receive an email with further payment information. I did check the junk/spam folder too and nothing has showed up.
Same here got the original confirmation email, but not after that.
